Studying normal infant development is a challenge for cognitive scientists in general and for neuroscientists in particular because: (1) physiological indices of infant cognition are generally noisy and technically difficult to obtain; and (2) interindividual variability and a paucity of established results make data interpretation very complex,…

This paper presents an updated cost-benefit analysis of the High/Scope Perry preschool Program, using data on individuals aged 40. Children were randomly assigned to a treatment or control group.

This paper addresses Lawson's puzzlement about the absence of prediction in William Harvey's and Marcello Malpighi's views on capillaries. In addressing the context of that enquiry, it also addresses historiographic versus philosophical models of science, contexts of discovery versus justification, normative versus descriptive interpretations of…

The field of environmental education research has been moving away from scientistic and positivistic discourses for some time now ("Environmental Education Research," 2000; Hart & Nolan, 1999).

Educators are bombarded with data from all directions, but to effect change in the education field, they must be able to determine what key information and data are needed, understand how to use what they have learned from the data, and then use what they have learned to improve overall student achievement. Collecting and using data has become an…

Practice-as-inquiry refers to the blending of instructional practice with systematic curricular inquiry. College and university teachers, while experts in their disciplines, typically are not specialists in instructional practice. Practice-as-inquiry (also referred to as teacher-as-researcher) may function as a mechanism of continuous teaching…

The term "research paper," in the sense of researched paper, is a tautology: all expository discourses are researched in some way. One of the first duties of writing instructors is to help students see the difference between reporting on information that already exists about a topic, in what is sometimes referred to as a "library…

Keeping writing center records is perhaps the director's most dreaded chore, and it is often seen as a negative duty detracting from the more important business of helping tutors and student clients. However, research data that computers now make almost instantly available reveals surprisingly positive results and ways of presenting those results…

This study explores the interpretation of two types of flow diagrams composed of different visual elements intended to communicate the same meaning.

When assessing relative probabilities, students were equally…
